How activation works: Your license is purchased and processed by Lemon Squeezy, our Merchant of Record, then activated in-app with a license key bound to your device (HWID). See the Terms of Service for activation limits and license scope, and the Refund Policy before purchasing.
Your card statement: Because Lemon Squeezy is the merchant of record, the charge on your card or bank statement will appear under "Lemon Squeezy" (or a similar Lemon Squeezy entity name) rather than "Atout Audio."

FAQ
Pricing questions
No. Atout Audio is a one-time purchase that unlocks the full feature set on your license, not a recurring subscription.
One license key is active on one (1) device at a time, bound to that device's hardware (HWID) rather than a user account. Switching to a new computer? Use the built-in Reset Device feature to deactivate the old device and activate the new one — this can be done once every 30 days. See the Terms of Service for full details.
Payments are handled by Lemon Squeezy, acting as our Merchant of Record. They manage checkout, taxes, and receipts on our behalf; Atout Audio never stores your card details. Your card statement will show a Lemon Squeezy entity name rather than "Atout Audio."
See our Refund Policy for details on eligibility, especially around downloaded and activated licenses.
